Clinical trial Recruiting at 7 sites Phase 3 Interventional Ages 18 and up

AI tool helps dermatologists decide if a skin lesion could be melanoma

Official title: Pragmatic Randomized Controlled Trial of Artificial Intelligence for Melanoma Diagnosis (PRACTA-MEL) (AI)

Run by Memorial Sloan Kettering Cancer Center · NCT07890415 · Data updated 2026-11-12

A computer tool called DEXI tested with DermaGraphix Visualizer helps dermatologists see if a skin lesion might be melanoma and aims to reduce unnecessary biopsies.

Is this trial a fit for you?

Likely a good fit

Adults (18+) who are undergoing an in-person dermatology visit at a participating site and have a mapped ICD-10 code related to skin tumors or other specified skin conditions.

Probably not a fit

Patients whose lesions are clearly benign or clearly malignant may not experience a change in biopsy decisions.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 3 trial evaluates whether the DEXI artificial intelligence decision-support system improves melanoma screening in dermatology clinics. DEXI analyzes images and information to flag lesions that may be melanoma when used with the DermaGraphix Visualizer. Participants are adults undergoing in-person visits at participating sites, and clinicians use DEXI as part of real-time decision-making. The study looks at changes in biopsy decisions and melanoma detection rates compared with standard care. Lead sponsor is Memorial Sloan Kettering Cancer Center, with NIH and Canfield Scientific as collaborators, and data collection occurring at Stanford for the imaging component.

Why it matters

Potential benefit: If successful, clinicians may more accurately identify melanoma and avoid unnecessary skin biopsies.

How similar studies have gone: Prior work with AI-based dermatology tools has shown potential to assist lesion assessment, but results vary by setting and tool.
